Description

technical field [0001] The invention belongs to the field of stationery, in particular to ink and its fading solution, red ink and its erasing solution for writing, drawing or marking. Background technique [0002] At present, more inks have been used in daily learning and work to outline key content, but their functions are relatively single. For example, CN02142480.2 discloses a "fluorescent marking colorant and pen", that is, a fluorescent colorant used to mark objects, and CN201510914368 discloses "a waterproof ink", whose color is relatively stable during use. However, this type of ink has a single purpose during use, and it is difficult to meet the needs of different usage situations. [0003] CN2017110330652 discloses a "thermochromic ink and its preparation method", which can be applied to various temperature indicating devices in the industrial field. CN201410037404 discloses a "thermal elimination ink", which is mainly used for marking in the textile process. Th...
